IMPROVEMENT IN DRIVE-WELL TUBES.

The Schedule rcferrcdto in these Letters Patent and making part of thesame.

Hin-

v driven or tube wells; and- It consists mainly in the construction andnovel arrangement of devices intended toserve an eflicient purpose asthe lower section of such tube well.

A of the drawings represents a cylinder or tube constructed ot' wiresplaced. side by side, leaving very small openings or interstices yforthe passage of water therein.

B represents a solid inverted cone, having a slot at a, in which thepills c are passed through the lower rings of the tube, to hold saidcone in place. and allow lt sufficient play-room.

The'top of cone'B is made a little larger in diameter than the rings ofthe tube, so that the opening made thereby, when forced in the ground,shall be of sniijcient size to provide a lsmall circular chamber betweenthe surface of the cylinder and the side of the earth well.

I) 'represents rings, arranged respectively on the outside of cylinder Aat top and bottone-the upper one having a thread cutin its inner side,as shown, to provide means foifattachment to a section to be placed ontop thereof. 4 Y

E represents rings of galvanized iron, arranged rcspectively at the topand bottom ofthe cylinder A, in-

the manner shown.

By my method of arrangement, the wires that forml the cylinder A areclamped, both at top and bottoni, between `the rings I) and E, and aresoldered there securely.

I do not claim broadly a cylinder' of wires for use as the lower'sectionof a tube well, for I am aware. that JOHN M. IWIOT'IX' wires have beenused heretofbre for that purpose;y
